Asthe strand f qi-tant features of "the invention; ofavire is'held in this stationary:position,

a forming, block is brought into operation whereby it will bend one end of the wire upon 1tself- This-bent portionof the wire extends over a pro ecting lug and the latter is carried by a revolving shaft, so that by the turning of said shaft the bent end of 1 this wire'will be caused to movetherewith,

l in so rotating with said shaft the bent *tion of the wire will twist itself upon the "ly portion of the wire,- thereby drawing i self in place andv forming aloop. After this loop or eye has been formed the gripping blocks are released and the finished wire iscaused to pass through the table and fall within a tray or other suitable receptacle arranged beneath the table. \Vhen this operation has been completed at one side of the oscillating plate, the latter is caused to move in an ()JPOSltQ direction whereby another strand wire will be ripped and retained at the opposite side of this plate, and a similar mechanism will be brought into use for bending, twisting and looping one end of this strand of wire. Durting the continual operation of the machine the wires are fed to each side of. the osciliating plate where they will be gripped, bent, twisted, looped and subsequently-be deposited below the machine automatically and continuously.

The numeral 1 indicates a table which is supported upon the legs 2 and the latter are to be rigidly secured to a floor or other support to hold the table stationary.v J ourna led v within bearing blocks 3 supported upon the rounds of the table is a longitudinally extending shaft 4 having keyed to one end thereof a driving pulley-5 which may be connected to any suitable source of power for'rotating the shaft 4. J ournaled within the bearings 6 suspended from the table 1 by means of the arms 7 is a longitudinallyextending shaft 8 which is supported in a plane higher than the shaft 4 and to the rear side of the center of the table. Keyed,

to one end of the shaft 8 is a gear 9 adapted to mesh with a gear 10 carried by the shaft 4 wherebyupon the continuous rotation of the shaft 4 the shaft 8 will also be continuously rotated but at a lower rate of speed dflzo the gear connections 9 and 10. Arranged t.

Carried by the inner GIRLS of each of the shafts 21 are forming shafts 21 by means of the stud bolts 2',

looping blocks 23 which arekeyed to tlPe and the purpose of these forming blocks w' l also be later described. Secured to'the a 1r end of the table 1 by means of-the arms 5 are depending brackets 26 upon which :re mounted journal boxes 27 having journal d therein a transversely extending shaft 928. Keyed'to the inner end of the shaft 28 is a bevelgear 29 adapted to mesh with the Also keyed upon the shaft 28 is a mutilated gear. 'i

31 adapted to mesh with the mutilated gear;

32- Mounted upon the arms are beari in g blocks 33 in which is journaled a shaft34 i l having keyed thereto the mutilated gear.;32

and the inner end of this shaft- 34 has keyed thereto a gear 35. On eachside of therear ends of the oscillating pl'ate 11 are arranged bearing blocks 36 in which are journaled stud shafts 37 and 38 having the gears 39 and 40 keyed to their respective inner ends. These gears 39 and 40 are adapted to intermittently mesh with the gear 35 so that the shafts 37 and 38 will be rotated at intervals. Extending from each of the gears 39 and 40 are flanges 41 having recesses 42 in the periphery thereof. v withinthe arms 25 are stop pins 43 which are adapted to rest within the recesses 42 so as to hold one of the shafts 38 against rotation while the opposite shaft 37 is being rotated. The opposite ends of the shafts- 37 and 38 are cut away and have projecting Adjustably .mounte-d I from the flat faces thereof the lug projecping piston 48 secured to the inner end thereof. Arranged within the formed within the blocks 46 are coiled recesses e springs 49 having their outer ends adapted to rest against pins 50 carried by the rp dsr 47 whereby the grippingwill be I normally held within the recesses 51 formed within the gripping blocks 46. Secured to the inner face of eachof the gears 22 are cams 52, which are adapted to contact with the outer ends of the rods 47 whereby the rods willbe forced inwardly against the tension of the springs 49 and the gripping pistons forced outwardly against'the grip ing blocks whereby the Wires A .wil be gripped and held in astationary position.

'A' tray 53, as is better illustrated in Figs. 2

and 21, is mounted upon the table in front of the oscillating plate 11, upon which rest the forward or outer ends of the wires A.

Pivotally mounted as at 54 uponthe table .1 are crank arms 55"each having one end thereof connected to the legs 2 by means of the coiled springs 56. Within the opposite ends of these bell-crank levers 55 are journaled shafts 57 upon each of which are rotatably mounted apair of disks 58 and 59 between which and connected thereto are disks 60 having teeth arranged in the periphery thereof. Also pivotally mounted upon the shafts .57 are levers 61 each having a pawl 62 pivot-ally connected to one end thereof adapted to intermittently engage the teeth of the disks 60, and the opposite ends .of these levers 61, havepivotally connected "thereto depending arms 63. .Connected to the lower ends of the depending arms 63 and extending transversely of the table are levers 64 having their opposite ends connected to the table by means of the coiled springs 65. Thesecoiledsprings normally tend to hold the 'arms63 in a raised position thereby holding ,the\ springaactuated pawls 62 normally out of engagemei'it-with the teeth arranged iwithini the, periphery of the disk 60. Keyed ':11I)0I 1 tlie shaft'8 are sleeves 66 each having arranged thereon a cam 67 which cams are diametrically oppositely arranged with respect. to each other and which are adapted to engage' the levers 64: whereby the latter will lieoperated against the tension of the springs and the pawl 62 caused .to en- I gage the teeth of the disk 60 whereby said disk will be moved a short distance upon its axis thereby also causing the plates 58 and ,59 to belcarried therewith. The diam eters of the plates 58 and 59 are greater than thatof the disk 60 and the peripheries of'these plates are notched as at 68 and these notches are arranged in the plates so n w lie in alinement with each other. The extreme outer peripheries of these plates are. provided with the flat surfaces 70 arranged between the notches 68'. Secured within the forward end of the table 1 and thetray 53 is a shaft 71 having; journaled thereon a disk 72 provided with peri'pheral teeth adapted to engage theteeth of the left-hand disk 60, and also journaled upon the shaft 71 is a similar disk 73 having peripheral teeth adapted to engage the teeth of the right-handdisk 60 whereby upon the rotation of thedisks 60 the disks 72 and 7 3 will also. be rotated. Secured to the opposite faces of the 72 and 73 are plates 7-l aving feriphcral fiatlfajces '75 adapted to fiatfs'urfaces 77 0 of the ositi ns hees? disks 58 and 59 whereby when the pawl 62 is released fromthe teeth on the disk 60 the fiat surfaces 70 and 75 will be brought into contact thereby preventing the rotation of the disks 60, 72 and 73, but when the cam 67 is brought into contactwith the lever 6t and the pawl 62 brought into operation "these flat surfaces will be released as the shaft 57 upon which the disk 60is mounted is free to move when the resistance offered by the spring 56 has been released.

The wires A are manually moved from each side of the plate 11 and the tray 53 until the outer or forward ends of one of the wires res't within the alining notches 68.formed within the plates and 59.

forming blocks 23 and adapted to protrude beyond the lug extensions 76 are 'the form- These forming lugs 77 are ing lugs 77. L-shaped in configuration and have a pro-v truding arm 78 which is adapted to slide within a slot formed within the forming blocks Pivotally mounted as at 79 upon each of the depending supports 7 is a bellcrank lever 80 which is adapted to extend within the travel of a lug 81 formed upon the inner face of eaclrof the gear wheel's 18. The vertical arm .82 is adapted to engage the protruding arm 78 of the forming lug whereby the said forming lug will be forced back into the forn'iing block 23. Plates 83 are secured to the bearing blocks 20 and have projecting therefrom cam pro. jecting ends 8% which are adaptedfto extend within the travel of the varms78 so that when 'said arms strike said cams thefornr ing lugs 7 7 will be forced outwardly and when so forced to this outward position they will each remain at such position until the cam 8l-lifts thebell-crank lever 80 and causes the arm 82 to strike the arm 78 'so as to force the forming l ug77 back within the forming block 'hen one strand of between the gripping block sjl i and 1 ,8, j t lie plate 11 is oscillated by meaiis of the-cam 16 whereby the gripping blockliismoyed toward tliegripping block .{JCS 'and'HtheQ cam.

it will carry the inner bent end of the Wire ing lug 77 .back within the forming block 23 so that this lug 77 may pass around the looped end of the wire upon the continuous rotation of the forming block without com- 4 ing in contact therewith.

Adapted to be journaled withinthe' grip "ping blockdh is afsliaft carrying at one end thereof an arm 86.- Also keyed upon the shaft. 'is a gear 87-which is adapted to mesh. with a' reciprocating rack 88 journaled within the block 46, and the inner end of this rack 88v projects beyond the block' lfi as'at 89; Carried by the inner face of each of the gears 22 is a cam 90 which is adapted to engage the end 89 .of the rack-bar for forcingthe same inwardly against the tension of the coiled spring 91 and by so'moving the-rack-bar v88 the gear 87 'will'berotated therebyrotatingthe arm '86. After th eloopfhas been formed upon the end o'f the wire the cam 67 will again operate the leyer"6=i which in vturn will rotate the plates and 59 through the pawl" 62 as hereinbefore described thereby; releasing the wire on which a loop has just been formed and bringing another wire into "position to have a loop formed thereupon and as the wire is released from the gripping members and a loop formed thereupon thereby forcing the same from; the notches 68*within tl1e'di sks-58 and 59;;and permit tiag'the finished product to fall upon'the oor'or atray arranged beneath" the maohine' \Yherea'sthe looping operation of the machine'has' 'hereinbefore been described as beingperformed' atth'e right-halal side of 65 "the" oscillating p1ate.'itis of course/to be understood. that Whenthe plate p11 is oscil: lated in. an opposite direction the same operation will be effected atthe opposite side of the oscillating plate and in this manner the operator can continuously be feeding the Wires to each side of the os llating plate 11 with both hands and the loops are formed upon the ends of the Wires in a quick and. eiiicient manner f By having particular reference to Fig. 4 of the drawings :it will be noted that the gears and 32 are mutilated gears having the flattened. portions in their peripheries as indicated by the numeral 95 whereby upon the continuous rotation of the gear 31 the gear 32 will at intervals be held against rotation giving time at the proper interval for the gear 35 to change its mesh with either the gear 39 or 40 and the mutilated gears at this inter al act as. a, releasing mechanism'so that the gears 35, 39 and 40 may .mesh at intervals without stripping their gear teeth.

It will alsobe noted'from Figs. 2 and 3 of the drawings thatthe meshing gears 18 and 22 are also mutilated gears 'whereby the gear 18 may be continuously rotated but the shaft 21 will for ashort period he held against rotation after the loop-forming mechanism has performed its work upon each wire but at intervals. the gear 18 w ll mesh with the gear 22 for bringing the forming mechanism into operation.

Du'ring the operation of the machine power is continually supplied to the shaft i through the pulley 5 and the shaft 8 is caused to be revolved continuously but at a slower rate of speed than the shaft 4. Vhen the oscillating plate 11' has beenv swung upon its pivot connection 12 in the position as shown in Fig. 1 the continuously driven pinion 35 will engage the pinion 39" for re vol ing the shaft 37 and the shaft38 is held stationary and against rotation by, means of the pin 43 at the left-hand side of the machine. A- strand of wire' is then passed at the right-hand side of the plate 11..whei'e it- I will be gripped between the gripping blocks 45 a nd48, and one end of this strand of wire will rest within one set of notches (38 of the "revolving disks, whereas the opposite end of the. wire will project within the path of the revolving forming block. \Vhen having jiefe'rence to Figs. 15 to 18 inclusive it will be noted that upon each revolution of the forming block the )in 77 will be caused to' project outwardly tierefromwhere it will come in contact with the free inner end of the wire and as the lug lids-also projecting from the-side of the plate'll'the pin 77 will cause the free end of the wire to-bejbent illiflllldJlIG lu{ it until the free end of the wire bent back upon 1tself as shown-in lig. 16. then the 'pin 77 will be'releasc'd and caused to be passed back within the forming.

thewire until ,thenext, revolution of the forniingblock, As the shaft-37, is their causedtobe revol edand the lug 42L carried i Jtlierewith, the inner bent end of the wire A will also be caused to reyoli e, but the outer end Of-t-l-Wll1 is held {stationary and against rotation by-nieaiis of the gripping blocks laand LS, thereby causing the inner free lend of the wire to twist itself npon the body portion of the wire as shown in Fig'.

1S. \Vhen this operatitm is completed the disk til) at the right-hand side of, themai chine iscaustd to; advance one point in the @direction of the arrows as shown in Fig. 2 i 401 the drawings, due to the pawl and i'atcliet construction as. formerly described thereby 3 causing the finished wire to be rennin-ed from, one side of the oscillating plate. At

end of each wire is looped, and after this complete operation has been performed at each side of the plate 11 the finished product is automatically carried away from the table by means of the notched disks 58 and (30 until the wires are deposited below the machine ina suitable receptacle.

From the foregoing description taken in connection with the accompanying drawtliis art that I have provided a continuously workingmachine by which loops may be formed quickly and in an easy manner upon the ends of wires which may be used for tying bales together; but it is of course understood that by describing this wire working machine for forming loops upon wires to be used in connection with baling purposes, the wires may be used after being looped for any other suitable purposes.
